It is really a challenge to decide how much food to prepare for your graduation party.
If your open house is on a day with dozens of other parties, people may not be very hungry. The graduates and their parents will most likely have multiple parties to go to so they are not going to eat that much. However, relatives, friends, and neighbors attending just your party will eat more.
Food Formula: To help you determine how much food to serve you need to determine how many people will come that are hungry. Start by reviewing your invitation list. Divide the people into one of the following lists (A or B).
A List: Number of people you can count on to come hungry (close relatives, close friends).
B List: The rest of the people you are expecting and cut in half.
Add A and B lists together to determine the number of people you should plan to serve.
General Tips on food:
Limit your menu to five to seven items to keep it simple.
